The invention relates to a device for manufacturing a hydrodynamic groove bearing formed with pumping grooves. The device comprises a hard pin around which, or a hard sleeve in which, a cage is arranged which has one or more annular patterns of holes which are concentric with the pin or sleeve and which are engaged by hard balls which project from both sides of the cage. The pin or sleeve and the cage can be translated and rotated relative to each other, the balls bearing against a bearing surface of the pin or sleeve. The bearing surface is constituted by a groove bottom of a continuous groove which is concentric with the pin or sleeve, the groove bottom extending in longitudinal sectional planes of the pin or sleeve as an arc of a circle whose radius is at least equal to the radius of the balls.
